MARC/MODS data source: Duplicated records in MODS database but with differential data

[ronaldtse]

The latest release of the MODS database, since the switch from CrossRef information, at #42 , contains a number of duplicated records about the same bibliographic item, but there are data discrepancies.

We have discovered 417 duplicates when treating the URL as the primary key.

These discrepancies range from minor editorial changes (punctuation) to actual data corrections. Someone needs to go through these records to merge the changes into one item.

The detailed diff is provided here:

• detailed-diff.txt

The way to obtain this diff is:

$ git clone https://github.com/relaton/loc_mods.git
$ cd loc_mods
$ bundle
$ bundle exec bin/update-nist-mods
$ bundle exec exe/loc-mods detect-duplicates spec/fixtures/

The duplicates are physical representations of the electronic items; I will make sure I only include the electronic records in the next release.
